Hi Lohith
i have checked it in my test system and it worked. Honestly i don't know what might have gone wrong in your system. Anyway..since you have come to a conclusion on training your users to do the change it will work perfectly. Besides that it is always good to engage users in SAP system rather than creating programs that will do the work behind the scenes for them...Good decision from your part...
It was nice to have your feedback.
Cheers
